Mayo posted a note on his Twitter account late Monday night that he “will be signing” with Dallas.

Though there were no immediate details of the deal or announcement from the team, Mavericks owner Mark Cuban sent out his own tweet that read, “Welcome to the family OJ. We are fired up!!”

In 301 games over the past four seasons with the Memphis Grizzlies, Mayo averaged 15.2 points a game. Mayo was the third overall pick in the 2008 draft by Minnesota, who then traded him to Memphis in a seven-player deal.
